ABSTRACT:
Disclosed is an imaging method useful in facsimile transmission. The method involves passing an electrical current through a receiving member of a solid state persistent electrochromic material uniformly distributed on the surface of a substrate. The substrate comprises a surface material on a ground plane. The surface material is a material which becomes more conductive upon being heated or wetted and is returned to its original state of resistivity upon cooling or drying. The surface material is heated or wetted to increase its conductivity and thereby reduce its resistance to a level less than or about equal to that of the electrochromic material whereupon an electrical current is passed through the electrochromic material in imagewise configuration to thereby form an image. Upon formation of the image, it is fixed by cooling or drying the surface material.
